The error

Issue pinecone-io/python-sdk#151 (closed, 16 comments): Hi,
I want to install the grpc driver for pinecone, however as it need protobuf 3.19.3, it is not compatible with googles internal packages we are dependent on. I would like if someone could update the protobuf package to a later version 🙏
Way to test it is to try to install https://pypi.org/project/google-cloud-secret-manager/ in the same environment
